1 Claim.

This invention relates to a screw' top wrench, the general object of theinvention being to provide a device whereby screw tops of differentsizes can be easily removed from a jar or the like or placed in positionon the jar, with means whereby a pressure cap can be removed by thedevice.

'I'his invention also consists in certain other features of constructionand in the combination and arrangement of several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In' describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Fig. 1 is a plan View of the wrench.

Fig. 2 is an edge View thereof.

In this drawing, the numeral I indicates the substantially L-shapedmember formed with a straight shank having a substantially right angularpart 2 and the numeral 3 indicates the second member which is pivoted tothe part 2 as shown at 4, the two parts being reduced and overlappingeach other where the pivot 4 passes through them as shown moreparticularly in Fig. 2. The member 3 has a straight handle-formingportion 5, its intermediate part sloping slightly outwardly and towardthe part 2 as shown at 6 with the rest of .the member sloping inwardlyto the part 2 as shown at 1. 'Ihis member is formed with the teeth 8 onits inner edge, the teeth extending from a point adjacent the pivotalong the edge of the part 1 and over the major portion of the inneredge of the part 6. The member I is also provided with teeth 9 on itsinner edge, the teeth extending from a point opposite the point ofjuncture of the part 6 with the part 5 and'extending a short distanceinto the part 2.

Thus, by placing the toothed portions of the members I and 3 over ascrew cap or the like and moving the handle portions towards each other,the cap will be gripped between the two members so that it can bereadily turned onto a jar or the like or off from a jar. By making themember 3 of the shape shown, the device will iit different sizes ofcaps.

I also provide a curved hook I on the outer edge of the member I with aportion of the outer edge sloping outwardly toward the part 2 in asubstantially straight line as shown at I I so that this arrangementprovides means for removing a cap from a jar or the like which is heldon the jar by pressure or friction and by making the part I I as shownso that the cap can be removed without bending the same, so that it canbe put back in place and used until the contents of the jar 10 have beenused up.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claim. f

I claim:

A wrench of the class described, comprising a substantially L-shapedmember providing a straight long arm and a straight short arm, the inneredge of the long arm having a toothed portion which extends from a pointan appreciable distance from the free end of the long arm to a point onthe inner edge of the short arm a slight distance beyond the junction ofthe two arms, and a second member having an elongated straight handleforming part, an elongated substantially straight part having one endpivoted to the extremity of the short arm of the first member, saidsubstantially straight part of the second member diverging from thetoothed portion of the long arm of the first member and said secondmember having an intermediate portion connecting the other end of thediverging part with the inner end of the handle forming part andarranged at substantially right angles to the diverging part andextending inwardly from said diverging part, the inner edge of thediverging part and said intermediate part being toothed, whereby thespace between the toothed portions oi the two members graduallyincreases from the short arm to the handle portions, with the handleportions located close together.
